I have 20 open mares and 1 stallion that I would like to breed them to. Iwant to get them in foal early so I want to put them under lights. I need to manage the heat cycles so that all of the mares don't come in at the same time because the stallion will not be able to handle that. Anyone tell me the best way to manage this?

There's nothing much you can really do until the mares have had their first ovulation for the year. Once that's happened, you can start using hormonal manipulation. There are a couple of possibilities with that. One is to use Prostaglandin F another is to use P&E - follow those links for more details on both. Rather than using the daily-dose P&E that is discussed in that article, you might want to contemplate using the biorelease formulation of either P&E or Altrenogest that is available from BET Pharmacy in Lexington, as they will produce very similar results.

By using those drugs, you should be able to time your breedings a little better so that you are breeding perhaps only 2 or 3 mares a day.

Of course, if you have the option of AI, then you don't need to worry about any of that, as you should be able to breed somewhere around 8 mares (or more) from a single ejaculate if you get normal quality ejaculates from your stallion.

Thanks so much. I wish using the regimate was a little simpler. I always heard just put them on Rigemate for 10 days then give them a shot and bring them in. So many variables. Do you think that if a stallion has two mares in front of him that are both in Estrus, he will choose the one which is closer to ovulation. I think that that is a stretch. If she will stand he probably will not care. What do you think. Thanks so much for taking the time to answer.

In the heat of the stud season our stallions would quite often do 2-4 mares a day and get most in foal we would start him about 6am and give him 4-5 hours rest between each. so i think if your stallion has two mares in front of him he will not believe his luck

No. He'll choose the one that looks the best to him or the least resistant.
